A GtkProgress is the abstract base class used to derive a GtkProgressBar which provides a visual representation of the progress of a long running operation.
typedef struct _GtkProgress GtkProgress;
The GtkProgress struct contains private data only. and should be accessed using the functions below.
void gtk_progress_set_show_text (GtkProgress *progress, gboolean show_text);
gtk_progress_set_show_text is deprecated and should not be used in newly-written code.
Controls whether progress text is shown.
progress : |
a GtkProgress. |
show_text : |
a boolean indicating whether the progress text is shown. |
void gtk_progress_set_text_alignment (GtkProgress *progress, gfloat x_align, gfloat y_align);
gtk_progress_set_text_alignment is deprecated and should not be used in newly-written code.
Controls the alignment of the text within the progress bar area.
progress : |
a GtkProgress. |
x_align : |
a number between 0.0 and 1.0 indicating the horizontal alignment of the progress text within the GtkProgress. |
y_align : |
a number between 0.0 and 1.0 indicating the vertical alignment of the progress text within the GtkProgress. |
void gtk_progress_set_format_string (GtkProgress *progress, const gchar *format);
gtk_progress_set_format_string is deprecated and should not be used in newly-written code.
Sets a format string used to display text indicating the current progress. The string can contain the following substitution characters:
%v - the current progress value.
%l - the lower bound for the progress value.
%u - the upper bound for the progress value.
%p - the current progress percentage.
progress : |
a GtkProgress. |
format : |
a string used to display progress text, or NULL
to restore to the default format.
|
void gtk_progress_set_adjustment (GtkProgress *progress, GtkAdjustment *adjustment);
gtk_progress_set_adjustment is deprecated and should not be used in newly-written code.
Associates a GtkAdjustment with the GtkProgress. A GtkAdjustment is used to represent the upper and lower bounds and the step interval of the underlying value for which progress is shown.
progress : |
a GtkProgress. |
adjustment : |
the GtkAdjustment to be associated with the GtkProgress. |
void gtk_progress_set_percentage (GtkProgress *progress, gdouble percentage);
gtk_progress_set_percentage is deprecated and should not be used in newly-written code.
Sets the current percentage completion for the GtkProgress.
progress : |
a GtkProgress. |
percentage : |
the percentage complete which must be between 0.0 and 1.0. |
void gtk_progress_set_value (GtkProgress *progress, gdouble value);
gtk_progress_set_value is deprecated and should not be used in newly-written code.
Sets the value within the GtkProgress to an absolute value. The value must be within the valid range of values for the underlying GtkAdjustment.
progress : |
a GtkProgress. |
value : |
the value indicating the current completed amount. |
gdouble gtk_progress_get_value (GtkProgress *progress);
gtk_progress_get_value is deprecated and should not be used in newly-written code.
Returns the current progress complete value.
progress : |
a GtkProgress. |
| Returns : | the current progress complete value. |
void gtk_progress_set_activity_mode (GtkProgress *progress, gboolean activity_mode);
gtk_progress_set_activity_mode is deprecated and should not be used in newly-written code.
A GtkProgress can be in one of two different modes: percentage mode (the default) and activity mode. In activity mode, the progress is simply indicated as activity rather than as a percentage complete.
progress : |
a GtkProgress. |
activity_mode : |
a boolean, TRUE for activity mode.
|
gchar* gtk_progress_get_current_text (GtkProgress *progress);
gtk_progress_get_current_text is deprecated and should not be used in newly-written code.
Returns the current text associated with the GtkProgress. This text is the based on the underlying format string after any substitutions are made.
progress : |
a GtkProgress. |
| Returns : | the text indicating the current progress. |
gchar* gtk_progress_get_text_from_value (GtkProgress *progress, gdouble value);
gtk_progress_get_text_from_value is deprecated and should not be used in newly-written code.
Returns the text indicating the progress based on the supplied value. The current value for the GtkProgress remains unchanged.
progress : |
a GtkProgress. |
value : |
an absolute progress value to use when formatting the progress text. |
| Returns : | a string indicating the progress. |
gdouble gtk_progress_get_current_percentage (GtkProgress *progress);
gtk_progress_get_current_percentage is deprecated and should not be used in newly-written code.
Returns the current progress as a percentage.
progress : |
a GtkProgress. |
| Returns : | a number between 0.0 and 1.0 indicating the percentage complete. |
gdouble gtk_progress_get_percentage_from_value (GtkProgress *progress, gdouble value);
gtk_progress_get_percentage_from_value is deprecated and should not be used in newly-written code.
Returns the progress as a percentage calculated from the supplied absolute progress value.
progress : |
a GtkProgress. |
value : |
an absolute progress value. |
| Returns : | a number between 0.0 and 1.0 indicating the percentage complete
represented by value.
|
void gtk_progress_configure (GtkProgress *progress, gdouble value, gdouble hmin, gdouble max);
gtk_progress_configure is deprecated and should not be used in newly-written code.
Allows the configuration of the minimum, maximum, and current values for the GtkProgress.
progress : |
a GtkProgress. |
value : |
the current progress value. |
hmin : |
|
max : |
the maximum progress value. |
"activity-mode" property"activity-mode" gboolean : Read / Write
If TRUE, the GtkProgress is in activity mode, meaning that it signals something is happening, but not how much of the activity is finished. This is used when you're doing something but don't know how long it will take.
Default value: FALSE
"show-text" property"show-text" gboolean : Read / Write
Whether the progress is shown as text.
Default value: FALSE
"text-xalign" property"text-xalign" gfloat : Read / Write
The horizontal text alignment, from 0 (left) to 1 (right). Reversed for RTL layouts.
Allowed values: [0,1]
Default value: 0.5
"text-yalign" property"text-yalign" gfloat : Read / Write
The vertical text alignment, from 0 (top) to 1 (bottom).
Allowed values: [0,1]
Default value: 0.5
